Description OSIDB Bzimport 2026-03-12 15:14:01 UTC 
A Server-Side Request Forgery (SSRF) vulnerability was identified in Red Hat Quay v3.12.x within the Proxy Cache configuration feature. An authenticated organization administrator can supply an attacker-controlled hostname as the upstream_registry parameter when creating or validating a proxy cache configuration. Quay instantiates a network connection to the supplied hostname with no validation against internal address ranges, private IP space, or cloud metadata endpoints.

Requirements to exploit: Attacker needs to be logged into the web app / initiate podman execution from host.

Component affected:
Mirror Registry for OpenShift – Proxy Cache configuration feature
Quay deployed on OpenShift 4.20 – Proxy Cache configuration feature

Version affected: latest releases
